O-ring is a synthetic rubber seal made by copolymerizing butadiene and acrylonitrile. It is a synthetic rubber with good oil resistance (especially nitrile rubber alkane oil) and good aging resistance. There are five types of acrylonitrile content (%) in the nitrile rubber: 42-46, 36-41, 31-35, 25-3... read more
Under the condition of 100% humidity, the silicone O-ring can absorb and condense water vapor equivalent to 40% of its own weight. As a desiccant, the average pore size of silica gel is 24 angstroms (length unit). The o-ring can absorb moisture even when the temperature is greater than 105 ° C, but ... read more
First, the production process of large specifications and large size O-rings 1.When selecting large size O-rings, pay attention to the following technical details (1) Calculate the pre-stretch rate (piston seal) or pre-compression rate (piston rod seal), section shrinkage; (2) Pay attention to the c... read more
2.The oil resistance of nitrile rubber O-rings NBR rubber O-rings are resistant to most oils, especially to alkane oils. There are two types of oils: alkane oils and aromatic oils. Alkane oils refer to the molecular structure of the chain. Aromatic oils refer to the molecular chain containing benzen... read more
